Aetna modified CPB 0602 covering intradiscal procedures, effective September 26, 2025. Here's what billing teams need to do.
Aetna, a CVS Health company, updated Clinical Policy Bulletin 0602 governing intradiscal procedures. This coverage policy covers 11 CPT codes and 10 HCPCS codes — including CPT 22526, 62287, 0232T, and a cluster of allogeneic cellular injection codes (0627T through 0630T). If your practice bills for any disc-level interventions on Aetna members, this policy change deserves your attention before September 26, 2025.

Aetna Intradiscal Procedures Coverage Criteria and Medical Necessity Requirements 2025
The CPB 0602 Aetna intradiscal procedures coverage policy groups interventions into several distinct categories. Each category carries its own medical necessity threshold. That distinction matters enormously when you're building out documentation checklists and prior authorization packets.
The policy covers CPT 22526 (percutaneous intradiscal electrothermal annuloplasty, unilateral or bilateral, with fluoroscopic guidance) and CPT 22527 (add-on code for one or more additional levels). For these codes to clear a medical necessity review, your documentation needs to reflect conservative treatment failure and appropriate patient selection. Aetna prior authorization requirements for intradiscal procedures are not optional — submit your auth request with complete clinical records.
CPT 62287 covers percutaneous decompression of the nucleus pulposus by any method. HCPCS S2348 is the radiofrequency-specific version of the same procedure. These two codes are closely related but not interchangeable — using S2348 for a non-radiofrequency decompression will trigger a claim denial.
The allogeneic cellular injection codes — 0627T, 0628T, 0629T, and 0630T — cover percutaneous injection of allogeneic cellular and/or tissue-based products into the intervertebral disc. These are grouped with platelet-rich plasma (PRP) codes 0232T, 0481T, G0460, and P9020 under intradiscal growth factor and biologic infiltration. These biologics are where Aetna draws the sharpest lines on medical necessity.
MRI guidance codes 77021 and 77022 appear in the policy as related CPT codes. They're not standalone procedures here — they're supporting codes when image guidance is part of the intradiscal intervention. Bill them only when MRI guidance is documented as performed and medically necessary.
Aetna Intradiscal Procedures Exclusions and Non-Covered Indications
The billing risk in CPB 0602 lives in the biologics and regenerative medicine codes. Aetna groups 0232T, 0481T, 0627T–0630T, G0460, P9020, S2142, and S2150 under the same policy cluster as intradiscal injection of gelified ethanol (DiscoGel). That's a signal about how Aetna views these procedures — as investigational or unproven unless very specific criteria are met.
S2142 (cord blood-derived stem-cell transplantation, allogeneic) and S2150 (bone marrow or blood-derived stem cells, allogeneic or autologous) fall under this same grouping. These are high-risk codes. Submitting them without airtight medical necessity documentation and prior authorization is a fast path to denial — and potentially a recoupment demand down the road.
The TNF-inhibitor HCPCS codes — J0135 (adalimumab), J0717 and J1438 (etanercept), J1602 (golimumab), J1745 (infliximab) — appear as "other HCPCS codes related to the CPB." Their inclusion points to spondyloarthropathy diagnoses in the ICD-10 list (M45.0–M49.89 spondylopathies, M08.1 juvenile ankylosing spondylitis). These biologics are not intradiscal procedures — they're covered separately when medical necessity criteria for inflammatory spine disease are met.
If you bill intradiscal biologics and PRP codes frequently, loop in your compliance officer before the September 26 effective date. The grouping of regenerative injection codes with gelified ethanol (DiscoGel) is a red flag for how Aetna views coverage for these services.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Intradiscal electrothermal annuloplasty (IDET) | Review against criteria | CPT 22526, 22527 | Prior auth required; document conservative treatment failure |
| Percutaneous disc decompression (any method) | Review against criteria | CPT 62287, HCPCS S2348 | S2348 is radiofrequency-specific; do not use interchangeably with 62287 |
| Intradiscal PRP / platelet-rich plasma injection | Likely experimental/not covered without specific criteria | CPT 0232T, 0481T; HCPCS G0460, P9020 | High denial risk; document thoroughly or expect denial |
| Allogeneic cellular/tissue product injection, intervertebral disc | Likely experimental/not covered without specific criteria | CPT 0627T, 0628T, 0629T, 0630T | Grouped with DiscoGel/gelified ethanol in policy — investigational posture |
| Intradiscal injection of gelified ethanol (DiscoGel) | Likely not covered / experimental | Related HCPCS grouping | Not an FDA-approved procedure in U.S. commercial markets |
| Stem cell injection — cord blood, allogeneic | Likely not covered | HCPCS S2142, S2150 | High recoupment risk without documented criteria |
| MRI guidance for intradiscal needle placement | Covered as supporting code | CPT 77021, 77022 | Bill only when MRI guidance is documented as performed |
| Inflammatory spondyloarthropathy (TNF inhibitor biologics) | Covered under separate criteria | HCPCS J0135, J0717, J1438, J1602, J1745 | Not intradiscal procedures — covered for diagnoses M45.0–M49.89, M08.1 |
| Postlaminectomy syndrome (M96.1) | Diagnosis code in scope | ICD-10 M96.1 | Used with intradiscal procedures when clinically applicable |
| Degenerative disc disease / dorsopathies | Diagnosis codes in scope | ICD-10 M43.0–M43.9, M50.00–M54.9 | Primary diagnostic support for intradiscal procedure claims |
Aetna Intradiscal Procedures Billing Guidelines and Action Items 2025
| # | Action Item |
|---|---|
| 1 | Audit your charge capture for all affected codes before September 26, 2025. Pull a 90-day claims history for CPT 0232T, 0481T, 22526, 22527, 62287, 0627T, 0628T, 0629T, 0630T, 77021, and 77022. Compare your current billing patterns against the updated CPB 0602 criteria. Fix any systematic mismatches now — before the effective date. |
| 2 | Separate your radiofrequency decompression billing from general decompression billing. CPT 62287 covers percutaneous nucleus pulposus decompression by any method. HCPCS S2348 is specifically for radiofrequency-based decompression. Review your charge capture templates to confirm the right code routes to the right claim. Swapping these two produces a claim denial that's entirely avoidable. |
| 3 | Flag the allogeneic cellular injection codes (0627T–0630T) for mandatory prior authorization review. These codes carry the highest denial risk in the policy. Update your prior auth workflow to require medical necessity documentation before scheduling. Your authorization team should know that Aetna groups these codes with gelified ethanol injections — that tells you how skeptically they'll review the request. |
| 4 | Update ICD-10 pairing protocols for your intradiscal procedure codes. The diagnosis codes in this policy span M43.0–M43.9 (deforming dorsopathies), M45.0–M49.89 (spondylopathies), M50.00–M54.9 (other dorsopathies), and M96.1 (postlaminectomy syndrome). Make sure your charge capture links each CPT or HCPCS code to the most specific, clinically supported ICD-10 code. Unspecified or mismatched diagnosis codes are a leading reason for medical necessity denials on spine procedures. |
| 5 | Do not bill MRI guidance codes (77021, 77022) as standalone services on intradiscal claims. These codes belong on the claim only when MRI guidance is performed and documented as part of the procedure. Billing them routinely as add-ons without supporting documentation will draw a medical necessity review. |
| 6 | Separate your TNF-inhibitor biologic claims from intradiscal procedure claims. HCPCS J0135, J0717, J1438, J1602, and J1745 are in scope for CPB 0602, but they apply to inflammatory spondyloarthropathy diagnoses — not to disc-level injection procedures. If your practice bills both, make sure the claims are structured correctly and the diagnosis codes match the treatment pathway. |
| 7 | Talk to your compliance officer if you bill PRP or stem cell intradiscal injections regularly. HCPCS G0460, P9020, S2142, and S2150 carry serious reimbursement risk under this policy. Aetna's grouping of these codes with DiscoGel injections — a procedure not approved in U.S. commercial markets — signals an investigational designation. A compliance review before September 26 is worth the time. |
